Description
Technical Field
The invention relates to the field of water environment, water ecology and water eutrophication treatment, in particular to a biological algae removal method based on microorganism and zooplankton proliferation.
Background
In the last century, in Europe, North America, south America, Africa and Asia-Pacific regions, 53%, 48%, 41%, 28% and 54% of lakes are in eutrophication states of different degrees, and 66% of lakes and reservoirs in China are in eutrophication states. One outstanding problem of water eutrophication is blue algae bloom outbreak, which causes the water quality and water ecosystem to deteriorate, the water supply cost to increase and the drinking water quality to be threatened by safety; especially, the excessive algae toxins have the greatest harm to the health of human bodies and are very difficult to remove. However, the critical factors and mechanism of the blue algae bloom outbreak are not clear at present, the related natural factors cannot be controlled, the human factors are difficult to change, and the technologies for prevention, control and treatment are not flexible or can be called as 'absolute' although a lot of technologies exist, so that the blue algae bloom control or treatment of the water body in the lake and reservoir is still a very difficult and important work.
at present, the existing cyanobacterial bloom control technology mainly focuses on in-situ repair or treatment. Such as classical or non-classical biological manipulation technology, aquatic plant and ecological floating island treatment technology, biological agent and chemical agent restoration technology, water pumping aeration restoration technology and the like. In the development aspect of physical algae removal technology equipment or devices (including ship type) separated from a water body, in China, due to annual outbreak of blue algae water in large lakes such as Taihu lake, nest lake and Dian lake, which seriously affects the urban water supply safety, national and local governments give high attention and fund support to the physical algae removal technology, so that relatively more related patent equipment and devices are provided. However, in the development of biological algae removal devices, few studies are currently conducted at home and abroad.
